OIL-GUARD FOR JOURNAL-BOXES.

SPECIFICATION forming part of Letters Patent No. 711,849, dated October21, 1902.

Application filed April 26, 1901.

To all whom it may concern.-

Be it known that I, FREDERICK HACH- MANN, a citizen of the UnitedStates, residing at St. Paul, in the county of Ramsey and State ofMinnesota, (whose post-office address is 599 Lawson street,) haveinvented certain new and useful Improvements in Oil-Guards for Journal-Boxes, of which the following is a specification.

My invention relates to improvements in means for preventing oil injournal-boxes being wasted through the opening around the axle; and tothis end it consists in the features of construction and combinationhereinafter specifically described and claimed.

In the accompanying drawings, forming part of this specification, Figurel is a vertical section of the inner end of the journalbox. Fig. 2 is asection on line a: 00 of Fig. 1 looking toward the oil guards and beingpartly broken away, and Fig. 3 is a detail view of my invention removedfrom the journal-box.

In the drawings, A indicates a journal-box.

2 represents the inside end wall of the j ournal-box, and 3 an innerparallel wall constituting an intermediate space in which are adapted tobe arranged dust-guards of any desired construction. 1

In connection with the wall 3 and adapted to prevent the oil wastingaround the axle into the dust-guard chamber is arranged my invention. Inthe form shown in the drawings this consists of the semicircular metalslide B, the upper wall 4 of the slide being conformed to the shape ofthe axle and provided with a suitable facing 7 and thedownwardly-extending walls 5 and 6 standing parallel with the oppositesides of the bottom of the wall 3. To prevent the oil passing from theinside of the journalbox underneath the slide, I secure a strip ofleather or other suitable material 8 to the inside of the slide, thesaid strip projecting downward below the bottom of the wall 6 andforming a close joint between the wall 6 of the slide and the adjacentface of the journal-box wall 3.

Secured to the inside of the slide B by range in connection with theslide means of a bolt 9 is the spring 10, the oppo- Serial No. 57,538.(No model.)

site ends of said spring bearing against the adjacent surface of thejournal-box wall 3. It will be evident that by means of this spring theslide is held tightly against the axle. The inner wall 5 of the slide iscurved inward, as shown, to form a spring and hold the opposite wall ofthe slide tightly against the wall 3 of the journal-box. I alsopreferably ar- B a simi larly-constructed slide 0, fitting over the wall3 at the top of the axle-opening. The slides B and 0 preferably overlapat the sides of the axle-opening, as shown, the overlapping ends of theleather facing 7 being cut, as shown in Fig. 2, to make the ends flush.

In using my improved device dust-guards of any desired construction areintended to be placed in the dust-guard chamber. The slides B and G arethen placed in the axleopening, as shown. When in place, the springs 10will hold the slides tightly against the axle and the spring member 5 ofeach slide will hold the inner wall of the slide tightly against thewall 3 of the journal-box, thus preventing any leakage of oil from the journal-box. Where desired, the upper slide 0 may be dispensed with andthe slide B alone used.

It will be evident that the construction shown may be modified withoutdeparting from the idea of the invention, the scope of which is definedby the following claims.

I claim- 1. In combination with the j ournal-box wall formed with anopening to receive the axle,

a metal slide arranged in said opening formed 8 5 with downwardly-bentsides fitting over the adjacent edge of the journal-box wall, afacing-strip secured to the outer face of said slide, and spring means.normally holding said slide against the axle.

2. In combination with a journal-box wall formed with an axle-opening, ametal slide arranged in said opening and formed with two downwardly-bentsides fitted against the opposite sides of the adjacent edge of the journal-box wall, and means for holding said slide against the axle.

3. In combination with the journal-box wall formed with an opening toreceive the axle, a metal slide arranged in said openingand formed withdownwardly-bent sides fitting over the adjacent edge of the journal-boxWall, a facing-strip held between one of said sides and the adjacentface of the wall, and spring means normally holding said slide againstthe axle.

4. In combination with the journal-box wall formed with an opening toreceive the axle, similar metal slides arranged in said opening, each ofsaid slides being bent to form parallel walls fitting over the adjacentedge of the journal-box wall, and spring means normally holding saidslides pressed against the axle.

5. In combination with the journal-box wall formed with an opening toreceive the axle, a slide arranged in said opening, outwardlyextendingflanges carried by said slide and fitting against the opposite sides ofthe adjacent edge of the journal-box wall, a facing carried by one ofsaid flanges, one of said flanges being bent to form a spring, and

spring means normally holding said slide pressed against the axle.

6. In combination with the journal-box wall formed with an opening toreceive the axle, similar slides arranged in said opening and fittingover the adjacent edge of the journalbox wall, the meetingedges of saidslides overlapping, and spring means normally holding said slidespressed against-the axle.

7. Incombinationwiththejournal-boxwall formed with an opening to receivethe axle, similar slides arranged .in said opening and fitting over theadjacent edge of the journalbox wall, the meeting edges of said slidesoverlapping, spring means normally holding said slides pressed againstthe axle, and spring means holding said slides tightly against the sidesof the journal-box wall.

In testimony whereof I afiix my signature in presence of two witnesses.

FREDERICK HACHMANN.
